Frequency dependence of microwave attenuation in spatially extended porous absorbents

Frequency dependence of microwave attenuation in spatially extended porous absorbents

The moisture absorbency of spatially extensive fabrics such as incontinence pads has been measured as a function of microwave frequency using a simple transmission method employing a network analyser. Results show a strong dependency of frequency and indicate that there is an optimum value of around...

Zusammenfassung:The moisture absorbency of spatially extensive fabrics such as incontinence pads has been measured as a function of microwave frequency using a simple transmission method employing a network analyser. Results show a strong dependency of frequency and indicate that there is an optimum value of around 10 GHz at which to develop low-cost specialist equipment for such measurements.
